If you're experiencing issues with your desktop background image in Windows, check that the original wallpaper hasn't been deleted or moved, or you're not running Windows in Safe Mode as Safe Mode disables the wallpaper feature. If you continue to have problems even after running these checks, a third-party program or a setting within the operating system is more likely to be to blame.
